Title
Care of Aluminum
The Aluminum Association Inc.
Publication Date:
Aug 1, 2002
Scope:
One of aluminum's most desirable attributes is its natural resistance
to corrosion. When the bare
metal is exposed to air, it readily combines with oxygen to form a
tough, transparent, protective
oxide coating. This oxide layer allows aluminum products to perform
virtually "maintenance-free" in
a wide variety of environments.
Aluminum can also be treated or "finished" in many ways. Painting,
anodizing and plating with other
metals can provide a variety of surface appearances and provide
further protection to the base
metal.
Apart from the purely aesthetic reasons for keeping aluminum surfaces
clean, there are also
practical reasons as well. In certain aggressive environments,
especially those containing salt,
excessive surface oxidation and pitting can occur. These can shorten
service life of the aluminum
by reducing its strength and promoting fatigue failures.
All the finishes, including the non-finished or bare, may be kept
clean and bright with mild soap
and water alone. However, if cleaning has been postponed for too long,
and the dirt is especially
tenacious, a more aggressive cleaner and cleaning technique may be
required.
This publication will provide insight into the proper methods and
materials to be used to maintain
the various finishes of aluminum products - from architectural to
transportation, from industrial
to home and recreational products. Sections include:
• tips to help identify surface finishes
• properties of various types of cleaners
• step-by-step care and cleaning procedures for a variety of
aluminum products
• proper handling and storage techniques for aluminum products
• a comprehensive list of commercially available cleaning
products and their producers
Aluminum is available commercially in at least seven different
finishes, each with its own
characteristics. Aluminum care and cleaning programs must, therefore,
be tailored to the metal's
finish as well as to the needs and conditions of service.
